Abstract:: Craniocerebral injuries were common in traffic accidents. Due to the complexity of rotating-caused injury experimental device, the rotation angular acceleration is difficult to be controlled accurately. Therefore, the relationships between brain rotational motion and craniocerebral injury and the related tolerance limits have yet to be studied. To solve the above technique problems, we design and construct an experimental platform of craniocerebral rotating crash. With the air pressure of 200 kPa, the peak angular acceleration was (19 615.2±75.9) rad/s2; with the air pressure of 400 kPa, the peak angular acceleration was (45 565.7±315.2) rad/s2. Through no-load experiment, this device was proved to be able to control the angular acceleration precisely under different air pressures.
